Variable linking?

How do I link a TGraalVar to another so when I change one the other reflects the change?

If you are talking of TGraalVar as object just use addcontrol and change vars reversibly at the child node with getparent?

Im talking nonsense... these are GUI functions. X_o

Well, script your own function. :>

I think b = a.link() might be what you are looking for, but I am not certain how well it works.

I've tried that about 10 times, and its never once worked so I came here to ask.

I did testing with .link() awhile back and was rather unsatisfied with the results I got.

HTML Code:

  this.var = 4;

  temp.var = this.var.link();

  temp.var++;

  echo("temp.var - " @ temp.var @ " this.var - " @ this.var);

Outputs: temp.var - 5 this.var - 4

HTML Code:

function onCreated()

{

  this.var = 1;

  getVar()++; // Works

  

  temp.var = getVar();

  temp.var++;

  echo("temp.var - " @ temp.var @ " this.var - " @ this.var);

}



function getVar()

{

  return this.var.link();

}

Outputs: temp.var - 3 this.var - 2

I would really like if this was fixed >_>

Well for normal variant variables (TGraalVar) the linking is undone once you assign them to some other variable, but it works as function parameter (passing arrays to a function which can modify it). It is not planned to make it work in other ways.
